A Newton is the amount of force that is required to increase the speed of a one kilogram mass by one meter per second each second that the force is applied
The area is mesured in square meters
Mesurment
Barometer
A barometer mesures atmospheric pressure by the atmosphere pushing down on a liquid and causing it to rise up a vacumed column where the pressure can be mesured by little tick marks on the tube.
